摘要： In an ultra-wideband communication system, a 1-trit ternary analog-to-digital converter (“ADC”) having dynamic threshold adaption and providing an output in ternary form [+1, 0, −1]. The ternary ADC includes a pair of 1-bit binary ADCs, one being configured in a non-inverting form, and one being configured in an inverting form. Each binary ADC includes an feedback network mechanism, thereby allowing for simultaneous and independent adaptation of the pair of thresholds, compensating for the effects of any DC offset that may be present. The use of a trit-based ternary encoding scheme improves system entropy.

摘要： To improve operability by a user in a case of performing data transfer wirelessly in a near area, a near-field wireless communication circuit 10 included in a terminal 1A is able to switch between a normal mode to perform OFDM and a near mode with a relatively short communicable distance as compared with that in the first communication mode and to perform spread spectrum. A controller 13 executes preliminary processing needed for initiating data transfer in the near mode with a terminal 1B serving as a communication destination between the terminals 1A and 1B by using the near-field wireless communication circuit 10 which is set to the normal mode. Further, the controller 13 determines availability of the data transfer in the near mode with the terminal 1B by using a measured value of communication quality which has a correlation with a communication distance to the terminal 1B as a measure of the determination. Furthermore, when it is determined that the data transfer in the near mode is available, the controller 13 initiates the data transfer with the terminal 1B by using the near-field wireless communication circuit 10 which is set to the near mode, based on a result of the preliminary processing executed in the normal mode in advance.

摘要： In order to implement novel utilization methods, implementation of a low power consumption and high sensitivity RF receiving system is desired. A microwave frequency band stub resonance booster circuit characterized by boosting the amplitude of an RF signal in a passive operation by resonating in series a 0.2 pF to 0.01 pF micro-capacitor element with a λg/2 open stub element to perform impedance conversion of the input RF signal is used. In addition, since a capacitor which has been conventionally inserted in order to repeat charging and discharging of the RF signal by using two diodes becomes useless by putting a DC resonant component of resonant-boosted output into an open state when voltage-doubling and rectifying the resonant-boosted RF signal, rectified output can be obtained and high-sensitivity reception and detection of the RF signal becomes possible without being affected by the capacitor which imparts comparatively large insertion loss.

A radio tag TGn includes: a characteristic impedance unit (3) for generating a response signal by using a pulse signal received from a broad-band antenna (1); a transmission path (2) having a predetermined length, transmitting the pulse signal received by the broad-band antenna (1) from the broad-band antenna (1) to the characteristic impedance unit (3), and transmitting the generated response signal from the characteristic impedance unit (3) to the broad-band antenna (1); and the broad-band antenna (1) for receiving the pulse signal and transmitting the response signal. The aforementioned pulse wave is transmitted to the radio tag TGn by the UWB method. The response signal from the radio tag TGn is received and the radio tag TGn is identified from the reception waveform.

摘要： Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.
